From b3d84af7cdfc079ef86d94f7cf125821559925fa Mon Sep 17 00:00:00 2001 From: Quentin Monnet Date: Tue, 25 Oct 2022 16:03:22 +0100 Subject: bpftool: Define _GNU_SOURCE only once MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit _GNU_SOURCE is defined in several source files for bpftool, but only one of them takes the precaution of checking whether the value is already defined. Add #ifndef for other occurrences too. This is in preparation for the support of disassembling JIT-ed programs with LLVM, with $(llvm-config --cflags) passing -D_GNU_SOURCE as a compilation argument.
